Abstract

Translated fromFrench

Antenne multifaisceaux à pointage réglable La présente invention concerne une antenne multifaisceaux (10) à pointage réglable comprenant un dispositif de réflexion (12) unique et une pluralité de sources rayonnantes disposées en regard du dispositif de réflexion (12) et aptes à émettre et/ou à recevoir des signaux radioélectriques, le dispositif de réflexion (12) définissant un centre, un plan focal et un foyer se trouvant dans ce plan focal. L’antenne (10) est caractérisée en ce qu’au moins l’une des sources rayonnantes, dite source mobile, est mobile sensiblement indépendamment de la ou de chaque autre source rayonnante dans une surface de balayage pour régler le pointage de l’antenne (10), la surface de balayage coïncidant avec le plan focal ou étant tangente à celui-ci au foyer. Figure pour l'abrégé : Figure 1The present invention relates to a multibeam antenna (10) with adjustable aim comprising a single reflection device (12) and a plurality of radiating sources arranged opposite the reflection device (12) and capable of transmitting and / or receiving radio signals, the reflecting device (12) defining a center, a focal plane and a focus lying in this focal plane. The antenna (10) is characterized in that at least one of the radiating sources, called the mobile source, is mobile substantially independently of the or each other radiating source in a scanning surface to adjust the pointing of the antenna. (10), the scanning surface coinciding with or tangent to the focal plane at the focal point. Figure for abstract: Figure 1
